Magdalene's Undoing

Week 36 Brings us Magdalene's Undoing. and YES i have found the history of this cube, so sit back hell fans and enjoy.

One of LeMarchand's many puzzle boxes to be found in the late 20th century, Magdalene's Undoing, was found on July 16th, 1970. It was uncovered in the Syrian desert by a group of British soldiers on war exercises, and is linked by some to the mysterious disappearance of Capt. Nathan Green. This man was last seen retiring to his tent with "The Regret Configuration" on the evening of its discovery, never to be seen again. The box itself disappeared from Capt. Green's tent the next day, and has only recently re-surfaced in Iran. There it was purchased from a street vendor, who clearly had no idea of its true worth, for the princely sum of $15.
This particular construct was crafted from the finest African ebony and inlaid with silver. Although recent research would suggest that it is in fact one of a pair (the other being ivory as a base and inlaid with osmium),
